An external bitcoind index management service module.
By default, this module includes a script, spents, transaction block, txout, tx, median time past and fee indexes.
The module uses getblockheader
, getblockhash
, getblock
and getbestblockhash
RPC methods for blockchain synchronization; and getrawmempool
for mempool synchronization.
-txindex
is not required for this module; but is still useful for individual transaction lookup (aka txHex
).
See https://github.com/bitcoinjs/indexd/issues/6 if you think an independent transaction index should be added.
Assumes yajrpc
is used for the provided bitcoind RPC object; and leveldown
for the database object.
When conveying block height, -1
represents unconfirmed (in the mempool).
null
represents unknown or missing.
For example, the height of the transaction ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
in the Bitcoin blockchain is null
(it doesn't exist!).
